While Applying patch on a 12.2.5 environment using online patch cycle in adop, Autopatch Failed with error

AutoPatch error:
Invalid password for schema "CUST1" (oracle_id = 20087)

AutoPatch error:

AutoPatch error:
aipspv(): Error setting up PDI list for upgrade

Root Cause
=========

Password for Application schema is not changed using FNDCPASS

Solution
========

1.Change the password of custom application with FNDCPASS 

Syntax for FNDCPASS

$ FNDCPASS apps/<PASSWORD> 0 Y system/<PASSWORD> ORACLE CUST1 <NEWPASSWORD>
Log filename : L********.log


Report filename : O*****.out

2. Verify the password change is successful

$ cat L*******.log

Working...
Password is changed successfully for user BOLINF.
FNDCPASS completed successfully.

Please Note, In 12.2.x Environments FNDCPASS must be executed on RUN Filesystem.

3. Restart the online patching cycle 

While restarting adop apply phase after a previously failed session, use options abandon and restart


adop phase=apply patches=123456 restart=yes abandon=no 

[Use this command if you wish to continue the previous patch session from the step where it failed]

adop phase=apply patches=123456 restart=no abandon=yes


[Use this command if you wish to start a fresh patch session]




If changing password using FNDCPASS does not work, analyse further details about database user and application user.

Check if the database user and application user are defined correctly using the sql queries below

SQL> select ORACLE_ID from FND_ORACLE_USERID where oracle_username like '%CUST1%';

 ORACLE_ID
----------
     2008

SQL> select application_id from fnd_application where application_short_name = 'XX1';

APPLICATION_ID
--------------
         2003

SQL> select * from fnd_product_installations where oracle_id=2008;


If the user details are not correct from the output of above sql, Please correct them.
